01

Crushing process

in general, the process pulverizing materials into granules whose sizes exceed 1-5mm called crushing. Impact force is applied to the material to reach the state of fragmentation. There is two-stage crushing and three-stage crushing process. Jaw crusher crushes materials primarily, and impact crusher or cone crusher crushes materials secondarily, then sand making machine will shape materials, finally final products are got.

02

Grinding process

According to materials’ characters and specific requirements, some materials should be ground to suitable fineness. Depending on input size and output size, you can choose Raymond mill, high pressure suspension roller mill, vertical mill, super pressure trapezium mill, etc. machines.
